Title: Vehicle suspension arrangements in combination with checking means therefor
IPC: B61F5/22
Filed: 1969-12-17
Abstract: 1287768 Checking vehicle suspensions KNORR-BREMSE GmbH 17 Dec 1969 [18 Dec 1968] 61567/69 Heading B7L The invention relates to a method of checking the air suspension system of a rail vehicle. The suspension is provided with level-regulating means and a control device dependent on curves for adjusting the height of pneumatic bellows 13, 14, the device being controllable by a constrained gyro 45, and comprising a compressor 27 which, in dependence on travel through a curve conveys air from bellows on the inside of the curve to bellows on the outside, switching valves being arranged in the suction and delivery pipes of the compressor for respectively shutting off and connecting these pipes to the bellows, and switching valves being provided for shutting off the level regulating means. The method operates as follows:- a step-by-step switch 43 starts at step 1 in plane I and an axle generator 41 is connected to relay 42. When the vehicle travels in a straight path, if the compressor 27 is operating correctly as supervised by a vacuum controller 36, the controller will operate a contact 69 and signal lamp 70 will be illuminated. When a minimum speed of travel is exceeded the gyro 45 starting up causes lamp 47 to light, thus indicating operation of the gyro. The remainder of the check can be carried out whilst the vehicle is stationary. The switch 43 is then moved to step 2 and a source of current 49 switches on relay 42 thus starting the gyro. Movement of the switch to step 3 energizes magnet 52 attracting armature 54 from its neutral position thus simulating a left-hand curve and the control arrangement of the suspension system operates magnetic valves thereof causing compressed air to be conveyed from the left to the right bellows. Correct operation thereof is indicated when the bellows close associated contacts 61, 62 allowing current from source 65 through contact 61, diode 67 and contact 62 to signal lamp 66. When the gyro reaches full deflection valves 21-24 and 30, 31 are de-energized so that controllers 34, 35 are de-pressurized causing contacts 61, 62 to open and lamp 66 to be extinguished. Switch 43 is then moved to step 4 causing electromagnet 52 to be de-energized. Resistance R 1  diverts voltage at tapping 57 of potentiometer 58 thus simulating tilting of the vehicle body. By means of springs 51 gyro 45 is re-centered and the control arrangement, by simulation of an exit from the curve, causes re-erection of the vehicle body and lamp 66 lights. As soon as the gyro reaches its central position the control interrupts the re-erection and lamps 66 and 68 are extinguished. Movement of the switch 43 to steps 5 and 6 simulate a right-hand curve and a similar procedure takes place. Hence the correct illumination of lamps 47, 66 and 68 indicates correct operation of the suspension. The checking may be carried out automatically.

Title: Measuring Electrophoretic Mobility
IPC: G04F10/04
Filed: 1978-08-31
Abstract: The electrophoretic mobility of particles is measured by applying a voltage to a liquid sample contained in an electrophoretic cell and by measuring the time taken for a selected particle to move a preselected distance between two set vertical markings formed on the screen of a monitor 4 supplied by a vidicon 1 which views the sample via a microscope system. An image scanning signal is digitalized by passing it via a filter and a comparator 6 with an adjustable reference voltage (Uref). This digitalized signal is supplied to a logic system along with image synchronization pulses and two line synchronization pulses. The various synchronization pulses define a "rectangle" to be transversed by a selected particle. The selected particle's path time across the "rectangle" (from vertical side to vertical side) is measured by starting and stopping the gating of signals from a clock 29 to a counter 30. <IMAGE>

Patent GB-2031914-A (GB)
Title: Particle boards
IPC: C08L75/04
Filed: 1979-08-28
Abstract: The use of polyisocyanates as binders in the preparation of particle boards is subject to the drawback that the boards exhibit a tendency to adhere to the face of the platens used in their formation. This problem is minimized by incorporating minor amounts of a mixture of certain mono- and di- (saturated or unsaturated aliphatic) acid phosphates or the corresponding pyrophosphates, into the polyisocyanate to be used as binder. The polyisocyanates and the acid phosphates and or pyrophosphates, are applied to the particles separately, or after preblending one with the other. Whether the components are applied separately or in combination one with the other, they can each be applied either neat or in the form of an emulsion or emulsions.

Patent GB-2075309-A (GB)
Title: Processing binary data framing
IPC: H04L7/04
Filed: 1980-04-29
Abstract: Frame information is recovered from a stream of binary data formed at a transmitter (1) from a block of m xn information bits comprising m groups of n bits plus m parity bits, one for each said group of n bits, these parity bits having then been scrambled by performing an exclusive-OR operation in a gate (5) on each parity bit with a respective bit of an m-bit parity scrambling code, said block of bits together with the scrambled parity bits forming a frame for transmission over a transmission link (3). At a receiver (2) new parity bits are produced in a parity bit generator (9) at the incoming bit rate from the incoming stream of binary data by forming a new parity bit from each successive moving group of n +1 incoming bits. The new parity bits are cyclically distributed to n + 1 m-bit shift registers (10,11,12,13), and a framing signal is produced when one of the shift registers (10,11,12,13) holdsm bits substantially corresponding to the m bits of the parity scrambling code.
